Farewell to Jenny Piggott - January 2011, All Stages

In the summer of 2010, Jenny Piggott retired as NRICH Director and we held a farewell event for her. Colleagues and friends joined us to work together on problems they had suggested. This month we are featuring some tasks that were inspired by the day.

This article discusses what happens, and why, if you generate
chains of sequences getting the next sequence from the differences
between the adjacent terms in the sequence before it, eg (7, 2, 8,
3) maps to (5, 6, 5, 4).

The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the
NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to
embed rich mathematical tasks into everyday classroom practice. More information on many of our other activities
can be found here.
